Silage bacteria agent for oat grass in alpine pastoral area

Abstract

The invention discloses a silage bacteria agent for oat grass in an alpine pastoral area. The silage bacteria agent is prepared by 4x109-5x109 CFU / g of pediococcus pentosaceus, 2x109-3x109 CFU / g of lactobacillus plantarum, 0.5-0.6 g / g of starch and mineral elements (0.02-0.04 mg / g of copper sulfate, 0.06-0.08 mg / g of magnesium sulfate, 0.8-1.2 mg / g zinc sulfate, 6.2-6.6 mg / g sodium acetate, and 0.8-1.2 mg / g sodium citrate). According to the silage bacteria agent for the oat grass in the alpine pastoral area, silage lactic acid strains adapting to local environmental conditions are separated and selected from artificially cultivated oat grass and soil in the area, compounding and application evaluation of the silage strains are carried out, the silage bacteria agent suitable for oat grass feeding processing in the alpine pastoral area is developed, the technical demand of high-qualified silage fodder concocting and processing is solved, and the technology level of efficiently conversing and utilizing artificial forage resources is effectively improved.

Description

technical field [0001] The invention relates to the technical field of agricultural breeding, in particular to an oat grass silage bacterial agent in alpine pastoral areas. Background technique [0002] The animal husbandry in the Qinghai-Tibet Plateau has completely different characteristics from the inland areas. Due to climate, agricultural development and other reasons, the animal husbandry in the Qinghai-Tibet region is still dominated by grazing, but the long winter has brought serious nutritional deficiencies to the overwintering livestock. Overwintering will cause livestock weight loss of 20-30% every year. The main reason is the seasonal imbalance of feed nutrition supply. Facing the grazing production mode with a wide area on the Qinghai-Tibet Plateau, we should learn from industrialized management methods such as centralized breeding in the inland and the use of modern concentrated feed. Due to reasons such as cost and tradition, it is also difficult to realize fo...

AI Technical Summary

Problems solved by technology

However, due to the special climate characteristics of "high altitude, cold, hypoxia, and drought" in this area, the application effect of silage inoculum products at home and abroad is not ideal. The traditional silage technology still used is relatively very primitive. Simple aerobic fermentation and anaerobic fermentation of microorganisms, the technology is backward, the growth rate of lactic acid bacteria is relatively slow, it is difficult to play an early inhibitory effect on harmful bacteria, resulting in a large loss of nutrients in the forage grass due to the pollution of bacteria during the silage process, It is not conducive to the efficient transformation and utilization of artificial forage resources in the area, and the effective preservation and improvement of nutritional components is limited
